Air compressor for hull cleaning

Am wondering if anyone has set up a small air compressor rig, 110V, similar to the ones used by divers for hull cleaning services. I assume just a small oil-less compressor and couple it directly to a stock dive regulator? I only need it dockside in a marina with 30A seervice. I've been using a diaphram type compressor for about 28 years. I think they call them "pancake" compressors now. Totally oilless, using a rubber diaphram. About 30 PSI max. It came with a 117 VAC motor, belt driven. I replaced the motor with a 12 VDC wheel chair motor for live-aboard use (take off the gear box and fit a pulley). Get an "old" regulator. Take off the 1st stage and disable the 2nd stage so you get free-flow. I bought some fittings/adapters so I use regular water hose as an air hose. If one wants to go this route, and have it run at 12 volts, a good "motor" to drive it is an original VW bug GENERATOR. Not an alternator. Connect the F (Field) terminal to the B (Battery) terminal. This is the +. The - goes to the case or ground terminal. This will draw about the same current as the wheel chair motor, about 10A, and give plenty of power.
